Are you publishing to the web from FileMaker Pro or FileMaker Server Advanced?
If from server, you should be able to check in the Admin Console.
From the FIleMaker Pro Host? Don't know if that is possible without some scripted help from a script that performs when the Web client logs on that would log the fact in a table.
Phil, I found this in the FileMaker Missing Manual but not sure how to apply it.
"While IWP is running, it can keep track of activity and errors. FileMaker keeps this information in log files in its Web Logs folder. The “Web activity” log records each
time someone interacts with the database. The log includes the person’s network address and the URL she requested. The “Script errors” log records errors in your FileMaker scripts. The “Web publishing errors” log holds other errors that occur in IWP, like invalid requests and missing databases. You can use these logs to see if
you need to fix your scripts, or to see who’s been using the databases and what problems they’ve encountered."
Not sure where to find "Web activity".
I don't know that such a log exists (I may be wrong about this) unless you are using FileMaker server Advanced to host the files.
